Ubuntu Server
Ubuntu is one of the most popular Linux distribution, both on server and desktop use. Although Ubuntu is a CentOS alternative it is from the Debian Linux family tree and it also uses various software packages that CentOS is not using. On the other way, Ubuntu is not an RPM-based Linux distribution. For using the RPM packages on Ubuntu, you can use Alien to convert the package into a DEB file. If you are 100% sure that Ubuntu meets all your demands and it is the best option for you, you can move from CentOS to Ubuntu but don’t forget, it is a really big decision.

Fedora Server
Fedora is sponsored primarily by Red Hat with additional support from other companies. It is another upstream source of the commercial Red Hat Enterprise. The community is centered around four principles, features, freedom, first, and friends. Fedora Server mainly focuses on modern data center technologies and allows to take control of all services and infrastructure. Fedora is a short-lifecycle community-supported server operating system.

OpenSUSE
openSUSE is also a very popular distro for both servers and desktops. It is sponsored by SUSE Software Solutions Germany GmbH and other companies. openSUSE comes with YaST -an installation and configuration tool- that provides an easy-to-use interface and powerful configuration capabilities.
